Frequently Asked Questions (FAQ)
-
Q: What is the difference between nominal and absolute filtration rating?
A: Absolute rating means the filter is tested to remove at least 99.9% of particles of a specified size. Our 5 micron absolute grade ensures consistent performance, whereas nominal ratings may allow more bypass. -
Q: Can this filter element be used with non-FRANKE housings?
A: Yes, the element has standard dimensions (2.5-inch OD, double open end or single open end with adapters). It is compatible with many standard filter housings. Please provide your housing details for confirmation. -
Q: What is the maximum differential pressure at 250°C?
A: The maximum differential pressure is 1.5 bar (21.7 psi) at 250°C. Higher differential pressure may cause structural damage. For operation near the limit, we recommend monitoring pressure drop regularly. -
Q: How often should the filter element be replaced?
A: Replacement frequency depends on the contaminant load and operating conditions. Typically, when the pressure drop increases by 2–3 times the initial value, replacement is recommended. Our elements have high dirt-holding capacity, extending life compared to standard filters. -
Q: Is the material food-grade or FDA-approved?
A: The phenolic resin fiber material is chemically resistant and can be used in certain food-contact applications, but we do not hold FDA certification. Please contact us for specific compliance requirements in your region. -
Q: What are the available length options?
A: Standard lengths are 10, 20, 30, and 40 inches. Custom lengths are available upon request – simply provide the required dimensions. -
Q: Can you provide samples before bulk order?
A: Yes, we offer sample orders. Please contact our sales team to discuss sample cost and shipping. -
Q: What is the typical lead time for this product?
A: For standard sizes, lead time is 10–15 working days. Custom orders may take 20–25 days. We ship from Tianjin, Qingdao, Shanghai, or Foshan ports.
